Tone synthesis apparatus and method

a tone and apparatus technology, applied in the field of tone synthesizers, can solve the problems of inability to reproduce the reed of an actual wind instrument faithfully, and it is difficult to synthesize tones sufficiently close to the reed of an actual wind instrument, so as to achieve accurate reproduction, and accurate synthesizing of tones.

Abstract

Tone synthesis apparatus synthesizes a tone of a wind instrument generated in response to vibration of a reed contacting a lip during a performance of the wind instrument. First arithmetic operation section solves a motion equation representative of behavior of the reed in an equilibrium state with external force acting on the lip and a second motion equation representative of behavior of the lip in the equilibrium state, to thereby calculate displacement yb(x), y0(x) of the lip and reed in the equilibrium state. Second arithmetic operation section solves a motion equation of coupled vibration of the lip and reed with calculation results of the first arithmetic operation section used as initial values of the displacement yb(x), y0(x) of the lip and reed, to thereby calculate the displacement y(x, t) of the reed. Tone is synthesized on the basis of the displacement y(x, t) calculated by the second arithmetic operation section.

Description

BACKGROUND

[0001] The present invention relates to a technique for synthesizing tones of wind instruments that generate tones in response to vibration of a reed.

[0002] Heretofore, there have been proposed tone synthesis apparatus of a physical model type (i.e., physical model tone generators) for synthesizing tones by simulating the tone generating principles of musical instruments. Among such tone synthesis apparatus are techniques disclosed in R. T. Schumacher “Ab Initio Calculations of the Oscillations of a Clarinet”, ACUSTICA, 1981, Volume 48 No. 2, p. 75-p. 85 (hereinafter referred to as Non-patent Literature 1); and S. D. Sommerfeldt, W. J. Strong, “Simulation of a player-clarinet system”, Acoustical Society of America, 1988, 83(5), p. 1908-p. 1918 (hereinafter referred to as Non-patent Literature 2). More specifically, Non-patent Literature 1 discloses a technique for simulating behavior of a clarinet by modeling a reed as a rigid air valve freely movable in its entirety, and No...
